Case Study: Reusable Bulk Dispensers Improve Efficiencies for PET Preforms on Production Lines
Esterform was one of the first players to notice the advantages of the Stackabox®. After they introduced the Stackabox for handling their lines of Purity Soft drinks, Esterform presented Stackabox to their customers as the standard primary packaging. Today, Stackabox bulk dispensing containers have become a common name in the world of PET preforms.
The Challenge
Esterform was looking for a better solution to store, dispense and transport preforms. The previous type of packaging entailed all kinds of difficulties. Some of the previous types of containers could only hold two-thousand preforms. Esterform is always looking for a more efficient way of production and every segment must keep up with the state-of-the-art handling systems. Alternative packaging was not collapsible, so the number of trucks returning the packaging was equal to the trucks delivering the preforms, transporting a lot of air. Esterform looked for a bigger, foldable container, with multiple dispensing possibilities, that would guarantee savings and hygienic storage, preventing damage such as neck breakage of the preforms.
The Approach
Stackabox offers multiple advantages over previous packaging formats for the storage and transport of PET preforms. The big container can hold around 10,000 38g preforms. The fully collapsible container can be erected by a single operator in 30 seconds before filling and has a fold-down ratio of 1/3.5. Thanks to the integrated lids, no extra wooden pallet underneath is required, eliminating risk for odor contamination, paper particles or wood splinters. If required, the Stackabox allows for liners to be easily placed and removed.
